To all whom it may concern.-

Be it known that we, STEPHEN T. HISLEY and JOHN A. MUNDY, of Syracuse, in the county of Onondaga, in the State of New York, have invented new and useful Improvements in a Machine for Forming Clasp- Tongues, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exactdescription.

This invention relates to the manufacture of the tongues of a certain species of clasps usually applied to arctic overshoes; and the invention consists in a novel organization of a machine by means of which the aforesaid tongues can be struck up into their requisite shape from blanks of sheet metal in a mostconvenient, expeditious, and perfect manner.

In the annexed drawings, Figure 1 is a front elevation of a machine embodying our invention. Fig. 2. is a side elevation of the same. Fig. 3 is a horizontal transverse section on line was, Fig. 1. Fig. 4: is a vertical transverse section on line y y, Fig. 3. Fig. 5 is a reversed side view of the stationary die and horizontally-reciprocating die. Fig. (3 is a detached side view of one of the cams of the crankshaft and end of the lever, which is actuated by said cam. Fig. '7 is a vertical transverse section on line ,2 a, Fig. 4. Fig. 8 is a plan view of a blank from which the clasp-tongue is formed. Fig. 9 is an edge View of said tongue complete, and Fig. 10 is a longitudinal section of the verticallyreciprocating die.

Similar letters of reference indicate corresponding parts.

A represents the bed of the machine, which is mounted on a suitable standard T, said bed being provided in its top with a recess 70, in which is firmly secured the stationary die a, which is formed with a groove a in its top, and with smooth horizontal bearings or seats I) b at opposite sides of the groove. Said groove is of the same shape in cross-section as the short bend m of the tongue 0. (Shown in Fig. 9 of the drawings.) In line with the groove Ct is a guide h, secured in a groovein the bed A. Said guide is formed with a chain nel, which is also in line with the groove a, and the surfaces at opposite sides of said channel are horizontal and form seats h h, coinciding with the seats Z2 b of the die a. In the guide It slides longitudinally the feedslide 1'.

At one side of the die a, and at right angles thereto or to the groove ct thereof, is a guidegroove 6 in the bed A, and in said latter groove slides longitudinally the die (I, which is in a plane immediately above the die a, and has the end which is over the die a formed with a face corresponding to the curvature or plane of the main portion m of the tongue 0.

The die (Z is forced inward and over the die a by means of a suitable spring, preferably of spiral form, as shown at f, which spiral surrounds a stem f, projecting horizontally from the outer end of the die (Z and through an upright arm of a bracket V, attached to the side of the bed A, as shown in Figs. 1, 3, 4, and 5 of the drawings. The spring presses with its outer end against the inner side of the bracket-arm and with the opposite end against a collar affixed to the stem f.

From the bed Arises a rigid upright frame B, which is provided with vertical guides 00, in which slides the plunger-head C, and to the bottom of the latter is connected the die 0, which has its lower or free end conformed to the shape of the groove a and is adapted to enter the same. The side of the die a facing the end of the die cl is conformed to the face of the latter or to the curvature or plane of the main portion m of the tongue 0. In the same side of the upper end of said die and its attaching-shank is a vertical channel n, drilled from the upper end thereof partway down, and a smaller channel extends thence down through the upper portion of the die, as shown in Fig. 10 of the drawings. In said channels slides vertically a dog 1*,of the form of a rod, having a collar 1)" affixed to it immediately above the smaller channel, and a spiral spring to surrounds the rod above the collar and bears upon the latter. The lower protruding end of the said dog is bevthe plunger-head C the shaft'D is formed with a crank or eccentric, preferably the former, as shown, and to the crank is connected the pitman P, the lower end of which is coupled to the head 0 in any suitable and well-known manner, preferably by means of a screw-threaded sleeve q, swiveled on the end of the pitman and screwed onto a screw- ,threaded stem 1 which is connected to the head 0 in any'suitable manner which will allow said stem to rock and conforinto the oscillation of the 'pitman. To the other projecting end of the shaft D are rigidly secured two cams F F.

The cam F consists of a wheel having its side obliquein'relation to the axis of thewheel, and'the cam F consist-s of a wheel having an eccentric-track on its periphery, as shown in Fig. 6 of the drawings. v

I're'presents a lever which is fulcrumed on abracket r, secured to the side ofthe frame -B. To the upper end of the said lever is pivoted a roller t, standing in a plane at right angles to thelever and held in contact with "the oblique side of the cam F by a'spring 1,

drawing the upper endof the lever toward the frame B. To the lower end of the lever I-is connected a'pit-man g, which is extended along the side of the die d, and is provided with an offset or notch g, by which it is adapted to engage ashonlder or lug Z projecting from the side of the die (1-.

A cam j is secured stationary to thebed A, and in the path of the. free-end of the pitmany, and has an "inclined face toward the pitm'an. Said cam'is of such a height that when'the end of the pitman g ridesupon thev top thereof said pitm'an is raised sufficient to. throw the notch g out of engagement with the lug Z. Another lever I is pivoted to the side of the frame B, and has pivoted to its upper end a roller 15, by'which it bears onthe' eccentric-track of the cam F at the rear of the latter, as shown in Fig. (5 of the drawings.

A spring r", connected to the lower end of the lever and to the frame B, causes the up-= per end of said lever to be thrown forward, and thus hold the roller t in contact with the cam.

'pivote'da bar 12, which I designate the castoff arm, for the reason hereinafter explained. Said bar or'arm is connected at one end to the lower end of the lever I by a stiff strap the cam j.

or link a, and the opposite en (1 or free end of said bar or arm is extended over the top of the die a.

The operation of our described machine is as follows: The cams F and F are so arranged in their operative posit-ions in rela tion to each other and crank of the shaft D as to cause the levers I I and plunger-head C to operate consecutively, in the order hereinafter stated. When the machine is atrest, the head C, with its die 0, is elevated, the die d is pushed back from over the die a by the pitman g, and the feed-slide t is drawn outward by the lever 19 sufficiently to allowa tongue-blank to be placed on the seats h h, between the inner end of the slide and adjacent side of the stationary die a, as represented by dotted lines in Fig. 3 of the drawin gs. Then by setting them'achine in motion the levers I and p push the slide 2' inward and cause the same to "push the "blank onto the top of the die a. The'head C next descends and causes the lower end of the die 0 to press a portion of the'blank'into'the' groove a, and in doing this the end portions ofs'aid blank are'caused to turn upward against opposite sides of-the die c. \Vhile this die is in the latterposition the lever I'pushes the pitman g still farther, until the end of thepitman comes in contact with and slidesupon This releases the lug Zof the cam d from the'pitman and allows said cam to be forced against'the side of the die c'by neans of the spring f, and by the stroke of thedie d the main-portion of the blank lying'between the dies 0 and d is bent to the shape of said 'of the die d. The die cl next recedesfrom the die 0 and allows the dog -v' to drop and bear on the back of the tongue 0, which by that time is completed. *Said tongue is thus retained on'the die (I, while it recedes from'the die a,which occurs immediately after the dog has engaged the tongue, as aforesaid. The slide t' having in the meantime been retracted by the levers Z and 19, another blank can be placed between it and the die a, and in the next advancing movement of the saidslide the cast-off arm 71, moving simultaneously with th'eslide and in front of it,'sweeps across the bottom of the raised die cand knocks the previously-formed tongue 0 off from said die and away from the machine in advance of the succeeding blank, which is pushed onto the top of the die a preparatory to receiving the impingements-of the dies 0 and d, in the groove a, conforming in cross-section to the short bend of the tongue to be formed, and the die 0, having its free end conformed to the aforesaid groove and adapted to enter the same, as set forth.
